Mechanical Technician (TTE Programme) - STI Group

  • Geneva, Switzerland
  • Full-time

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.

Job Description

Are you a technician looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge.  This position as a Mechanical Technician is part of our prestigious TTE programme. 

The Target, Collimators and Dumps section (part of the Sources, Targets and Interactions group) in the Engineering Department is in charge of the conceptual design, construction, operation and maintenance of special components having direct interaction with high-energy particle beams, so called “beam-intercepting devices”. Such devices are installed across the CERN’s accelerator complex, including particle-producing targets, beam absorbers/dumps, collimators, beam stoppers and slits.


As   Mechanical Technician, you will:

  • Support the various technical activities associated with the Beam Intercepting Devices managed by the section, among which conceptual design, assembly, installation and maintenance of targets, collimators and dumps. 
  • Support the LHC Injection dump design and assembly as well as the spare qualification, participate in the prototyping phase and follow-up on the procurement of various components. 
  • Ensure the appropriate link with the equipment control group (electronic control) as well as with the survey team for precise alignment of the devices.
  • Be involved in the routine maintenance as well as in the redesign and consolidation activities in the accelerator complex.


In order to qualify for a place on the programme you will need to meet the following requirements:

  • You are a national of a CERN Member State or Associate Member State (;
  • You have a Technical Diploma in the field of mechanics or equivalent (, and no more than 4 years' relevant experience after finishing your diploma;
  • If you are currently studying, you are still eligible to apply, although you are expected to have obtained your qualification by the start of your appointment at CERN;
  • If you hold a BSc or MSc, you are not eligible. However, you may be eligible for the Fellowship Programme.
  • You should have at least a working knowledge of English or French.

Specific skills required for this job:

Experience in:

  • Using CAD systems such as CATIA
  • Machining, assembling and testing precision mechanics
  • Reading mechanical design drawings and specifications in terms of tolerance.
  • Mechatronics implementation and execution

Additional Information

CERN would very much like to benefit from your expertise, commitment and passion.  In return, CERN will provide you with:

  • An employment contract of one year, renewable for a second year; 
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
